Description

Technical Field

[0001] This utility model relates to the field of drone performance technology, and in particular to a quick-release detachable holographic display device for multi-rotor drones. Background Technology

[0002] With the increasing maturity of drone technology, using drones for performances has become a novel and stunning performance method. Holographic display drones add holographic display devices to drones, enabling them to play holographic images for performances. Application number 202022791949.1 discloses a 3D holographic imaging drone. The 3D holographic imaging drone includes: a drone body, two first imaging units, and a second imaging unit. Both the first and second imaging units are electrically connected to the drone body. The two first imaging units are located on opposite sides of the drone body. The drone body has two tripods fixedly connected to the drone body. The second imaging unit is located between the two tripods. Each first imaging unit includes a first connecting rod fixedly connected to it. Each second imaging unit includes a second connecting rod fixedly connected to it and a hook. A first protrusion has significant damping between it and the inner wall of a first groove. The second connecting rod is installed in a second mounting groove. A second protrusion has significant damping between it and the inner wall of the second groove. The hook engages with the mounting block, facilitating the installation or removal of the first and second imaging units. This drone uses a single hook to fix a holographic fan. This connection method is not secure enough, and the holographic fan cannot form a proper image when the drone is moving due to its pseudo-holographic nature. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a quick-release holographic display device for multi-rotor drones. It employs three locking bayonets to connect with the drone, achieving both greater stability and quick-release separation while allowing for the mounting of larger holographic display devices. The device uses a universal joint to connect the holographic display module, ensuring that the holographic display device remains vertically downwards even when the drone is moving.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release detachable holographic display device for a multi-rotor drone, comprising a drone body, a locking module, a mounting module, and a holographic display module.

[0005] The locking module includes a top post, a locking cover, a rotating rod, a spring, and a mating surface. The mating surface includes a threaded hole and a hanging rod. The locking module is locked and fixed to the lower cover of the UAV body via a positioning screw passing through the threaded hole. The locking cover includes a locking latch, a locking cover hanging hole, a fastening buckle, and a top post hanging hole. The locking cover is connected to the top post via a hanging rod passing through the top post hanging hole, ensuring that the locking cover rotates around the hanging rod. The rotating rod includes a locking cover hanging rod and a mating surface hanging rod. The rotating rod is connected to the locking cover via the locking cover hanging rod passing through the locking cover hanging hole, ensuring that the rotating rod rotates around the locking cover hanging hole. The spring connects the top post and the mating surface. The mating surface includes a mating hole and a mating surface hanging hole. The mating surface is connected to the rotating rod via a mating surface hanging rod passing through the mating surface hanging hole, ensuring that the rotating rod rotates around the mating surface hanging hole. The locking cover, rotating rod, and mating surface are interconnected. When the mating surface moves up and down, the rotating rod drives the locking cover to rotate clockwise and counterclockwise, allowing the three locking covers to close and open.

[0006] The mounting module includes a fitting rod, a pop-out block, and a pop-out rod. The fitting rod includes a fitting surface latch, a pop-out hole, a locking nut, and a pop-out opening. The pop-out block is placed in the pop-out hole with its tapered cut surface facing downwards. The connecting rod of the pop-out rod passes through the pop-out opening, with the tip of the tapered head facing upwards and its lower surface parallel to the pop-out opening.

[0007] The holographic display module includes a spring, a fixed universal joint, a universal shaft, a floating universal joint, a motor, and an LED holographic display screen. The upper end of the spring is welded to the lower surface of the fitting rod, and the lower end is welded to the upper surface of the fixed universal joint, connecting the mounting module and the holographic display module. The left and right shafts of the universal joint are fitted into the fixed universal joint, allowing the floating universal joint to rotate in the front-back direction. The front and rear shafts of the universal joint are fitted into the floating universal joint, allowing the floating universal joint to rotate in the left-right direction. The motor is fixed to the bottom of the floating universal joint with fastening screws, with the motor facing downwards. The LED holographic screen is fitted into the motor, allowing the motor to drive the LED holographic screen to rotate. Fastening screws are used to securely connect the LED holographic screen and the motor, ensuring that the LED holographic screen will not fall off.

[0008] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0009] (1) The quick-release detachable holographic display device for multi-rotor UAVs uses a gimbal to connect the holographic display module and the mounting module. When the UAV moves, the use of the gimbal avoids the problem of reduced display effect caused by the holographic display module tilting together with the rotorcraft UAV upon initial connection. The holographic display module utilizes a 360° rotating holographic display screen. This holographic display method effectively avoids the limitation of the display angle imposed by LED fan holographic displays, effectively improving the UAV's maneuverability and enriching the performance content.

[0010] (2) The holographic display module and the drone application are detachable. This design allows for separation to reduce volume and facilitate storage. The quick-release design using three clips ensures sturdiness while greatly simplifying the installation and removal of the holographic display module, significantly improving operational portability and work efficiency.

[0011] (3) The locking module can be used directly as a tripod after being detached from the mounting module. The spring in the locking module has a certain shock absorption function for the tripod and can adapt to various ground environments for landing, greatly increasing its practicality.

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, a quick-release detachable holographic display device for a multi-rotor drone includes a drone body 1, a locking module 2, a mounting module 3, and a holographic display module 4.

[0030] like Figure 2 As shown, the locking module 2 includes a top post 2-1, a locking cover 2-2, a spring 2-3, a rotating rod 2-4, and a mating surface 2-5.

[0031] like Figure 3 As shown, the top post 2-1 includes a threaded hole 2-1-1 and a hanging rod 2-1-2. The locking module 2 is fastened to the drone body 1 through the threaded hole 2-1-1.

[0032] like Figure 4 As shown, the locking cover 2-2 includes a locking buckle 2-2-1, a locking cover hanging hole 2-2-2, a fastening buckle 2-2-3, and a top post hanging hole 2-2-4; the locking cover 2-2 is connected to the top post 2-1 through the hanging rod 2-1-2 passing through the top post hanging hole 2-2-4, ensuring that the locking cover 2-2 rotates around the hanging rod 2-1-2.

[0033] like Figure 5As shown, the rotating rod 2-4 includes a locking cover hanging rod 2-4-1 and a mating surface hanging rod 2-4-2; the rotating rod 2-4 is connected to the locking cover 2-2 through the locking cover hanging rod 2-4-1 passing through the locking cover hanging hole 2-2-2; ensuring that the rotating rod 2-4 rotates around the locking cover hanging hole 2-2-2; the spring 2-3 connects the top post 2-1 and the mating surface 2-5.

[0034] like Figure 6 As shown, the mating surface 2-5 includes a mating hole 2-5-1 and a mating surface hanging hole 2-5-2; the mating surface 2-5 is connected to the rotating rod 2-4 through the mating surface hanging rod 2-4-2 passing through the mating surface hanging hole 2-5-2, ensuring that the rotating rod 2-4 rotates around the mating surface hanging hole 2-5-2; the locking cover 2-2, the rotating rod 2-4 and the mating surface 2-5 are interconnected; when the mating surface 2-5 moves up and down, the rotating rod 2-4 drives the locking cover 2-2 to rotate clockwise and counterclockwise, and the three locking covers 2-2 can close and open.

[0035] like Figure 7 As shown, the mounting module 3 includes a fitting rod 3-1, a pop-out block 3-2, and a pop-out rod 3-3.

[0036] like Figure 8 As shown, the fitting rod 3-1 includes a fitting surface buckle 3-1-1, a pop-out hole 3-1-2, a locking nut 3-1-3, and a pop-out opening 3-1-4. The pop-out block 3-2 is placed in the pop-out hole 3-1-2 with its tapered cut surface facing down. When locked, insert the mating surface buckle 3-1 into the mating hole 2-5-1 and push it upward to move the mating surface 2-5 upward. At this time, because the mating surface 2-5 is connected to the rotating rod 2-4, the rotating rod 2-4 moves upward at the connection point with the mating surface 2-5. The length of the rotating rod 2-4 remains unchanged, and the connection point with the locking cover 2-2 moves downward, causing the locking cover 2-2 to close until the locking male buckle 2-2-1 and the locking female buckle 3-1-3 are engaged. At this time, the fastening buckle 2-2-3 between the locking covers 2-2 is tightened, and the spring 2-3 is compressed because the mating surface 2-5 is pushed upward by the mating rod 3-1. In order to resist deformation, the spring 2-3 applies vertical downward pressure to the mating surface 2-5, so that the mating rod 3-1 is firmly locked by the buckle. At the same time, the fastening buckle 2-2-3 provides a secondary safety mechanism for a secure connection, preventing accidental unlocking due to high-frequency vibration of the UAV. The locking module 2 and the mounting module 3 are connected (see...). Figure 9 and Figure 10 ).

[0037] like Figure 11 As shown, the connecting rod of the ejector rod 3-3 passes through the ejector hole 3-1-4, so that the tip of the conical head faces upward and the lower surface is parallel to the ejector hole 3-1-4; when the lock does not disengage (see...) Figure 12Due to the gravity of the holographic display module 4, the ejector rod 3-3 is pulled down, causing the lower surface of the conical head to align with the ground of the ejector hole 3-1-4. The ejector block 3-2 is pressed in when the locking module 2 and the mounting module 3 are closed, without applying an outward pushing force to the locking cover 2-2. When the lock is to disengage (see...), Figure 13 The drone descends vertically, placing the holographic display module 4 on the ground. Due to ground support, the holographic display module 4 no longer exerts force on the ejector lever 3-3. The drone continues to move vertically downwards, causing the conical head of the ejector lever 3-3 to move upwards, contacting the ejector block 3-2 and pushing it outwards. The ejector block 3-2 exerts an outward pushing force on the locking cover 2-2. Because the weight of the holographic display module 4 is reduced, the downward force on the locking latch 2-2-1 decreases, allowing the locking latch 2-2-1 to disengage from the locking nut 3-1-3 under the pushing force of the ejector block 3-2. The locking module 2 is then completely detached from the mounting module 3 (see...). Figure 14 After disengagement, under the elastic force of spring 2-3, the mating surface 2-5 returns to its initial position. Since mating surface 2-5 is connected to rotating rod 2-4, the point where rotating rod 2-4 connects to mating surface 2-5 moves downwards. The length of rotating rod 2-4 remains unchanged, so the point where rotating rod 2-4 connects to locking cover 2-2 moves upwards, causing locking cover 2-2 to separate by a certain distance, allowing it to be used directly as a drone landing gear. Spring 2-3 in locking module 2 provides some shock absorption during drone landing. When landing on uneven ground, locking cover 2-2 will continue to open after being supported by the ground and the drone's weight. Spring 2-3 is stretched, applying elastic force to mating surface 2-5 to control the locking mechanism, stabilizing the landing gear and enabling it to adapt to various terrains.

[0038] like Figure 15 As shown, the holographic display module 4 includes a spring 4-1, a fixed universal joint 4-2, a universal shaft 4-3, a floating universal joint 4-4, a motor 4-5, and an LED holographic display screen 4-6. The upper end of the spring 4-1 is welded to the lower surface of the fitting rod 3-1. The lower end of the spring 4-1 is welded to the upper surface of the fixed universal joint 4-2. The left and right shafts of the universal shaft 4-3 are fitted and connected to the fixed universal joint 4-2, allowing the floating universal joint 4-4 to rotate in the front-back direction. The front and rear shafts of the universal shaft 4-3 are fitted and connected to the floating universal joint 4-4, allowing the floating universal joint 4-4 to rotate in the left-right direction. The motor 4-5 is fastened to the floating universal joint 4-4 with fixing screws. After the motor 4-5 is fitted and connected to the LED holographic display screen 4-6, it is connected with fastening screws and secured with double nuts to prevent it from falling off.
